Xiaomi phone constantly writes “not enough memory”: what to do

The situation where your Xiaomi suddenly reports that the vacant space is over is familiar to many users.The pop-up notification screen can appear at the most inopportune moment: while shooting a video, updating an app or installing a new game.This message means that the system partition or user storage is critically filled, which can lead to slowing down the interface and even freezing the device.

In Android, which runs the MIUI or HyperOS shell, not only does it require space for files, but it also requires temporary operations to function properly. If the phone says there is not enough memory, the system blocks the creation of new temporary files, which causes errors in the application work, and this cannot be ignored, because overflowing storage reduces the life of the drive.

Solving the problem requires a comprehensive approach, from simple garbage cleaning to in-depth analysis of what exactly is clogged with your device. In this article, we will examine all the methods of freeing up space, from standard tools to advanced settings that will help return the smartphone performance.

Storage occupancy analysis and search for hidden files

Before you delete something blindly, you need to understand what exactly takes up precious gigabytes. Often users are surprised to find that half of the memory is occupied not by photos, but by messenger cache or system logs. Xiaomi's built-in tools allow you to study the structure of the storage in detail.

To start with, you should use a standard analyzer. Go to Settings → About Phone → Memory (the path may vary slightly depending on the version of MIUI). Here you will see a color diagram where each sector is responsible for a specific type of data: applications, images, video, audio, etc. By clicking on a specific sector, you can get a detailed list of files.

Particular attention should be paid to the Download folder and hidden messenger directories. Telegram and WhatsApp have a habit of storing all the media files viewed in memory of the device, even if you have already seen them.

• 📂 Check the folder. DCIM →.thumbnails – there are miniatures of the gallery, which can take several gigabytes.
• 💬 Go to the storage settings. Telegram/WhatsApp Clean the cache without removing important chats.
• 🗑️ Use the built-in Security app to scan for duplicates.

⚠️ Note: When cleaning system folders like Android/data Be careful. Deleting files from unknown directories can cause application settings to reset or malfunction.

After the initial analysis, it will be clear where the main “eaters” of space are hiding, and if most of the system files are occupied, this may indicate an error in the work of updates or a accumulation of debugging logs.

Cleaning the cache and temporary files of the system

Temporary files are created to speed up applications, but over time they cease to be useful and turn into digital garbage.Cache cleaning is a safe and effective procedure that does not affect your personal data, passwords or saves in games.

The easiest way is to use the built-in Cleanup tool in the Security app. However, for a deeper cleaning, you can use the Recovery Mode menu. To do this, turn off your phone and press the button combination (usually Volume Up + Power). In the menu that appears, select Wipe Cache Partition. This action will delete the system cache without affecting user files.

Also worth checking is the cache of the Google Play Store and Google Play Services. These system components often accumulate errors and temporary files that interfere with the correct operation of the app store. Go to Settings → Apps → All applications, find the Google Play Store, select Memory and click Clear Cache.

It's important to distinguish between Clear Cache and Clear Everything. The second option will completely reset the app to factory status by removing your logins and settings. To free up space, we only need the first option. Regular prevention helps keep the system on top.

Removing duplicates and heavy media files

High-resolution photos and videos are the main enemy of free memory on a modern smartphone; 4K or RAW images can take up 50–100 MB each, and often with frequent shooting and editing, copies and duplicates of the originals are left in memory.

The Gallery app on Xiaomi has a built-in tool to find similar images. The algorithm analyzes images and suggests leaving only the best options by removing blurred or repetitive frames, which allows you to free up a significant amount of space without losing important memories.

Remember the shopping cart. In modern versions of MIUI, deleted files don't disappear instantly, but instead move to a 30-day shopping cart, and to make room, you have to go to the Deleted album and clean it up completely.

• 📸 Use cloud services (Google Photos, Yandex.Disk) to store archives, leaving only recent pictures on your phone.
• 🎥 Check the Screenshots folder – there are often hundreds of unnecessary interface images accumulated there.
• 🎵 View the Audio folder – Old voice recordings and downloaded music can take up gigabytes.

If you're a video editor, check your project folders. High-resolution drafts can weigh a lot. Once you're done editing, you'd better migrate the source to your computer or the cloud.

Management of applications and their data

Apps tend to grow, social media, news aggregators and browsers cache content to load quickly, but over time, this cache becomes redundant, and many users store apps that they haven't used for months.

Do a software audit. Go to Settings → Apps and sort the list by size. You will be surprised to find that a simple game can take 5 GB and a browser can take 2 GB. If the application has not been used for a long time, it is better to remove it.

Some apps, like Spotify, YouTube, or Netflix, are characterized by the accumulation of offline content. Check the settings of these programs: you may have downloaded playlists or movies to watch on an airplane, but you haven't watched them for a long time. Deleting downloaded content inside apps is a quick way to get free space.

⚠️ Note: Do not remove system applications marked as “Secure” or without a “Delete” button. MIUI and lead to a cyclical reset.

Also worth paying attention to is the App Duplicates feature, which is that if you installed the second version of the social network (for example, through App Cloning), it takes up a separate place and caches data regardless of the main one, and check if you need both copies.

Use of cloud technologies and external drives

If internal memory is crowded but you don’t want to delete anything, you should consider expanding storage. Xiaomi is actively integrating cloud services that allow you to store data remotely, freeing up space on the device.

Mi Cloud (or Xiaomi Cloud) offers synchronization of contacts, notes, photos and voice recorders, and by enabling the option “Storage Optimization”, you can only leave thumbnails of photos on your phone, and the originals will be stored in the cloud, saving up to 90% of gallery space.

For models that support microSD cards, the problem is even easier: you can transfer all photos, music and documents to an external map. SD-The card so that new images do not occupy internal memory.

Modern cloud storage, such as Google Drive or Yandex.Disk, also has smart download features. Files are displayed on the list, but don't physically take up space on the phone until you open them.

Radical measures: resetting and reflashing

If the phone continues to write “not enough memory” even after a thorough cleaning, it may be a file system or system failure that helps to completely reset the data to factory settings.

Before you do this, make sure to back up all your important data. Reset will delete everything: contacts, messages, photos and installed apps. The phone will return to a "out of the box" state.

Settings → About the phone → Reset settings → Erase everything

After reset, take your time to restore all applications from backup. Often it is the old settings and cache of restored programs that clog up memory again. It is better to configure the phone as new and install only the necessary software.

💡

Before resetting your settings, take screenshots of important screens with Wi-Fi passwords and two-factor authentication to avoid losing access to your accounts.

In rare cases, when even a reset doesn’t help and the system writes about a lack of space immediately after turning on, it may be necessary to flash the device through the computer using the Mi Flash utility.This is a complex procedure that requires an unlocked bootloader, and it is recommended only for advanced users.
